Professional Applications & Engineering Value
These 2-56 UNC flat head screws with nylon patch locking address critical vibration-induced failure points in precision assemblies. Engineered from 18-8 stainless steel with passivated finish, they resist chemical exposure and galvanic corrosion in electrical enclosures, aerospace components, and marine equipment. The Class 3A thread fit ensures zero back-out security in high-cycle machinery, while the 82° countersink angle creates seamless joints in sheet metal and plastic fabrication. Ideal for industrial applications requiring permanent fastening solutions that withstand thermal cycling from -65° to 250°F without compromising 70,000 psi tensile strength.
Specification Summary & Compliance
Manufactured to UNC coarse thread standards with Class 3A thread fit precision and right-hand threading. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety in global supply chains. Dimensional accuracy maintained with 0.086" thread diameter, 3/8" length, and standard flat head profile for consistent performance across batch productions.
